Edge curl and lay flat issues are a problem in the label
and converting industry. Uneven moisture stratification can
cause shrinkage or expansion of cellulose fibers. Curled stock
is a problem for printing and packaging. Coatings can also
get thinner or thicker at the edges. A NIR transmitter cross
directional web profile greatly helps to reduce curl or coating
issues and improve process control operation.

The MCT transmitter shines NIR light wavelengths,
selected specifically by PSC, for the measurement and application
being performed, typically 1.94? for moisture or water based
coatings and 2.34? for hydrocarbon depositions or film thickness.
The NIR light is then directed onto the product being measured,
normally a moving web and measures the returned energy to
provide a calibrated display of percent moisture, GSM, #/ream
or other engineering units. Additionally, IR web temperature
can also be built into the MCT Nova Series Transmitter.

Guardian CD Web Profile System
Industry Standard
The Guardian Profile System connects to a PC with a 19”
Display at a Central Console. Larger displays, up to 65”,
for multiple scanners and measurements, can be integrated
into a single distributed system. The Guardian System can
also be operated manually or via a Human Machine Interface
(HMI).

Entry Level Profile System
Process Sensors Guardian Cross Direction Web Profile System
can be as simple and inexpensive as an automatic scanning
frame with 12” Operator Interface (OI) for profile display
and controls mounted on frame end.

Simple Cross Direction Scanning
System with Digital Display
This system allows for automatic scanning across web or jogging
to fixed position for machine direction
measurement and display on a 5.7” touch screen with
alarms, alerts and analog and digital outputs.
